ABB DSBC173A S100 Series Bus Extender Module
The ABB DSBC173A, also cataloged as the 3BSE005883R1 Bus Extender Module, operates as a dedicated hardware component for backplane bus propagation across multi-rack I/O configurations within ABB Advant and Master automation platforms. It bridges the primary system motherboard to auxiliary subracks over the S100 I/O bus, ensuring continuous physical and electrical signal routing across distributed rack assemblies.

Deterministic Backplane Communication Velocity & I/O Density Scaling
The DSBC173A maintains backplane bus communication velocity during multi-rack data transfers, preventing signal reflection and phase skew over extended installation distances. Internal signal amplification circuitry supports maximum I/O density scaling by allowing additional expansion subracks to execute synchronized logic cycles without introducing bus communication latencies. Firmware flash compatibility across parent CPU modules ensures seamless protocol pass-through and uncorrupted address decoding throughout the extended S100 network.
Frequently Asked Questions
Q: Does replacing an existing bus extender with part number 3BSE019216R1 require backplane modification?
A: No. Part number 3BSE019216R1 serves as the direct physical and functional replacement for both 3BSE005883R1 and legacy ID 57310001-KH within standard S100 I/O racks.
Q: Can the DSBC173A bus extender module be hot-swapped during active system control loops?
A: No. Removing or inserting a bus extender module interrupts the active S100 communication bus, which triggers system bus errors; power down the affected subracks prior to module swap out.
Q: How does the module maintain signal integrity across separate rack subframes?
A: Integrated bus driver components condition and balance high-speed logic lines, compensating for line capacitance and suppressing noise across rack-to-rack interconnect cables.
Field Installation Guidelines
- De-energize the main rack chassis and secondary expansion subracks before inserting or removing the DSBC173A module.
- Wear an ESD protective wrist strap connected to cabinet frame ground to prevent static damage to logic pin arrays.
- Align the circuit board card edges with the designated subrack guide rails and slide the card steadily until the rear edge connector seats fully into the backplane pin assembly.
- Tighten the top and bottom front panel retaining screws to ensure proper mechanical bonding and ground path stability.
- Verify that all inter-rack expansion cables are properly strain-relieved and routed away from high-current AC motor leads or variable frequency drive cables.
